Abstract

La presente invenzione si riferisce ad un processo per la granulazione di un fertilizzante denominato nitrato ammonico, avente un tenore di azoto compreso fra il 25% ed il 34%, mediante formazione di impasti di NH4NO3, calcare e/o dolomia, solfato ammonico e/o fosfati ammonici e MgSO4, addizionato in uno qualsiasi dei suoi abiti cristallini e dei suoi differenti gradi d'idratazione, seguito da operazioni di granulazione o prilling e di raffreddamento.The present invention relates to a process for the granulation of a fertilizer called ammonium nitrate, having a nitrogen content of between 25% and 34%, through the formation of NH4NO3, limestone and / or dolomite mixtures, ammonium sulphate and / or ammonium phosphates and MgSO4, added in any of its crystalline clothes and its different degrees of hydration, followed by granulation or prilling and cooling operations.
